Resumen

A new and simple spatial images method has been implemented for the numerical calculation of the Green's functions in circular cylindrical enclosures. The technique is based on the imposition of the boundary conditions for the potentials, using a spatial images arrangement. Results show that the numerical convergence of the novel technique is attained fast. They also demonstrate that the new Green's functions lead to accurate results when analyzing real structures. The technique has been used for the efficient analysis of practical planar circuits shielded in circular cavities.
